help to id a non-catfish

[dmcat]

Hi! Today is not a catfish related question, if possible. A week ago I obtained a group of nice characins and was wondering on their identity. They fairly large, around 6-7 cm. No details on origin. I would appreciate if anyone from catfish community could help to id them or refer to the resource where someone can help. Thanks ahead, DM

Hello

May be Tetra anostomus, Tetra chalceus or Tetra araguaiensis.

Hah! That middle picture, the characin looks like a gourami because of the catfish barbles.

Thanks for your replies! I have looked on the images of those Tetragonopterus species and they don't look like mine tetras. Color and eye size (?) are different. Originally I was thinking on some species of Moenkhausia but couldn't find a match. Now I am thinking that it might be a species of Astyanax... but again no proof. I would appreciate any other opinions. I hope someone had similar before.

And yeah, that Ompok eugeneiatus made that characin looks like gourami Hahaha

Thank again,
DM
